Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which the reaction takes place according to the simple linear regression model with equation y = 4.10 - 0.01x and o = 0.07. n USE SALT (a) What is the expected change in reaction time for a 1°F increase in temperature? For a 9°F increase in temperature? 1°F increase hr g°F increase hr (b) What is the expected reaction time when temperature is 190°F? When temperature is 260°F? 190°F hr 260°F hr (c) Suppose five observations are made independently on reaction time, each one for a temperature of 260°F. What is the probability that all five times are between 1.39 and 1.61 hours? (Round your answer to four decimal places.) (d) What is the probability that two independently observed reaction times for temperatures 1° apart are such that the time at the higher temperature exceeds the time at the lower temperature? (Round your answer to four decimal places.)

2. An engineer studied the relationship between the input and output of a production process. He considered the non-linear regression model: y = In (x + B1) – In ( Bo x). - In order to estimate the model parameters using a statistical software, the engineer needs to transform it to a linear equation. (a) What transformation is needed? U = the transformed X Both X and Y need to be transformed. Denote: V = the transformed Y What are U and V? (as functions of X and Y) (b) After the variables were transformed according to your answer in Part (a), the following parameter estimates were obtained: Intercept: 0.4 Coefficient of U: 1.8 What would be the estimates for Bo and B1 in the original non-linear model?
